You need to keep the polarity reversed on both speakers. I cut off the connectors from the adapter and then spliced them back on after reversing them. All of the speakers in the 6 base system have polarity reversed.
If you add a aftermarket amp, does any of this matter?@7LParker As usualI concur with @Patsy1099 ’s post, except you said the Kickers would be 88db not 81db, so they might be ok. I’ll leverage an old post format to predict how much volume those speakers you chose should generate. As a reminder I find my JL C2 volumes to be well balanced so I will use them as a (subjective) baseline; note I did not install amps or DSPs so this is just for a simple speaker swap.
First the 3.5” dash speaks: Need to make sure the quoted sensitivity ratings are all at the same power setting... drat! Kicker only gives 1W sensitivity, 88db. To compare we’ll have to adjust the others from the 2.83W spec I had originally checked.
- JL C2 3.5s = 4 ohm w/ 83 dB at 1W86 dB (at 2.83 W)
- Infinity 3032s = 3 ohm w/ 88 dB at 1W (estimated from spec)91 dB (at 2.83 W)
Not only lower impedance but also higher sensitivity. Therefore I would estimate the Infinity speakers to be about “two volume clicks” (~6 dB) louder than my 3.5s- @7LParker your Kicker 44KSC3504 = 4ohm 88db at 1W
Like the Infinitys 3032s, your dash Kickers would be louder than my JLs, but maybe by only “1.5 volume clicks” due to the higher impedance
Next the 6x9s, as spec’d at 2.83W:
- JL C2s = 4 ohm 96 dB
- Infinity REF-9633 = 3 ohm 93 dB
- Infinity Kappa 93ix = 2.5 ohm 96 dB
I would expect the Infinity 9633 volume to be close to the PowerBass and JLs. Also higher impedance is nicer for your amp.I would expect the Kappa 93ix to be louder than all the other 6x9 options we discussed by “a notch”, so they actually might balance better with the louder Infinity 3.5s if you are sold on those... but at a higher price.- Rockford P1692 = 4 ohm 94 dB Fronts
- Rockford P1694 = 4 ohm 93 dB (estimated from 1W spec) Rears
In both cases I would predict the Rockford 6x9s to be “1 click” quieter than my JL 6x9s
Conclusion: The numbers would predict that by combining the louder dash speaks with quieter doors it MAY result in overly loud dash/quiet doors. Two caveats though: 1) sound is subjective and you may actually prefer a louder dash than I do and 2) if you install an amp and/or DSP you can easily balance all six signals to your liking.
Hope that helps!
I believe with the base system you need to add base blockers to the tweeters I did in my 2017 worked great
I wouldn't say you must if you listen at moderate volumes, but I don't...
they are certainly a good idea if you don't want to blow those little speakers.
Well if you stick with four channels (and still run the fronts in parallel), regardless where your amplification comes from it would be advisable to balance the output of your door and dash speakers. Now if you go up to six channels you could set it all up to adjust their output separately and save these worries.
Yep you've got the impedance, sensitivity, volume relationship correct, A+ @sman301 ! Since I didn't have sensitivity ratings for the stock speakers it was hard to predict an exact volume match so some guessing/trial and error was required.

There’s a large rubber grommet above and to the left of the brake pedal. There is already wires coming through. You can poke/cut an additional hole and run your wire thru
The link to your build does not appear to be working. I've previously read through it but can no longer access it.Hey - good luck with your system, it can be a real bear.
You don't need to mess with the mic wires, I strongly recommend you get a PAC wiring harness, it gives you all the pigtails you need from the head unit (tapped under the driver seat). Those go into the DSP, and from there RCAs to the amps.
For remote I tapped an ignition source at the fuse box. I think it was #66?
I put a lot of details and pictures in my build thread, check that out and PM me if you have issues along the way.
5,000 Watt stereo upgrade from 8.4 6-Speaker non-nav | 5th Gen Modifications/Accessories
First off, I'd like to thank everyone who has contributed their own stereo projects and pictures on this forum - without this resource the project would have been much more difficult to plan and execute. In particular the posts of what to expect behind the backseats, in the door panels, etc...
If it sounds good to your ears I’d leave well enough alone.
same here, 9 channel I thought was a unconnect 12 issue, and that often was bundled with ET.
